This invention relates to window channels such as those used to hold and guide a sliding glass sash, and pertains more particularly to the channel lining which resiliently supports 5 and cushions the sash in the channel. One object of theinvention is the provision of a lining of the class described which is simple in construction, inexpensive to manufacture,

and effective in use.

Another object is the provision of an eco-' nomical channel of the above character constructed to provide cushioning pads arranged to engage and resiliently support a sliding glass sash, and adapted for use with materials of a relatively inexpensive nature.

A further object of the invention is the provision of a lining of this kind formed with tubular resilient cushioning portions having woven surfaces ofa durable and fric- 2 tion reducing character for contacting with the glass sash, and provided with resilient fillers or cores.

A still further object is the provision of such a lining woven to form two or more tubu lar portions filled with a resilient material, with flexible parts intermediate said tubular portions to facilitate bending-of the lining into channel shape, and with marginal portions for attachment to suitable stiffening and supporting means to hold the lining in shape and in position in the window runway.

To these and other ends the invention resides in certain improvements and combinations of parts, all aswill be hereinafter more fully described, the novel features beingin the channel, showing the position of the various cushioning pads;

Window runway channels with various types of linings are known, but some of these linings are so constructed as to be lacking in durability, while others require materials of a comparatively expensive character. It is the object of the present invention to provide a suitable lining for this purpose which'is efiicient in operation, durable in construction, and comparatively inexpensive to manufacture and install.

Referring nowto the drawing, the lining, in the present embodiment, is in the form of A a strip of textile material bent into channel shape, and woven to'form cushioning pads 16 and 17, hereafter described, which are arranged to resiliently support and cushion a sliding glass sash 18. Flexible parts or breaks 19 are provided intermediate the pads to facilitate the bending of the strip intochan; nel form for insertion in the window runway. "The pads 16 are preferably terminated short of the free edges of the strip to provide thin 'flexible marginal portions 20 for attachment to suitable stiffening, and supporting means,

hereafter described, to hold the lining in shape and in position in the runway.

Referring now to Fig. 4, there is shown .an enlarged fragmentary sectional view of the strip from which the channel lining is formed; This strip is of a textile material 25 and weft or cross strands 26 and 27 inter-- v sash 18, while the plies Bl'extend outwardly -to engage the lining supporting member, as

a upper ply and and comprises warp or longitudinal strands locked with 'the warp 'strands in any known or suitable manner. At predetermined por-. tions, the strip iswoven to provide the cushioning pads 16 and'17, whi'ch,in the present.

invention, are of a tubular ,confistruction formed in a manner to be presently described.

In the preferred embodiment of-the inven-' tion, the tubular at predetermined portions, to provide a tubular construction with spaeed upper andlower-plies and 31 respectively, as shown in The plies 30 of the tubular portions are arranged to extend inwardly to engage the glass shownin Fig. "1. Inth'e detailed construction illustrated in Fig. 4, only two adjacent weft strands .are shown, one forming the the adjacent strand forming the lower ply. This is for the purpose of clearness only, as it is to be understood that a multiplicity of weft strands, such as 26 and 27-, are employed to form a continuous tubu lar wovenportion extending the fulllength of the strip, as indicated for example in Figs.

' 4d strands 35, which cooperate with the plies 30,

are preferably of relatively heavy material densely arranged, as shown in Figs: 3- and 4,

and cooperate with the weft strands 26- to provide asmooth, durable, closely woven surface on which thesash 18 may easily slide.

The outer'or channel engaging surface of the pads, on the other hand, receives little or no wear and 'may,"there fore, 'be formed with a looser or more open surface construction.-

' For this reason andto reduce the cost of such linings, the warp strands 36 which engage the weft strands 27 of the plies 31 are preferably of smaller diameter and ,less densely arranged than the warp strands 35, as clearly .illus- $5 trated 1n Flg. 4. Thestrands 36 'may also beof a less expensive charactenthan the strands '35 so -asto further reduce the cost of7'such a lining.-

.The resent invention also provides'resil-i-J ent filhng means for the tubular portions .or

pads 16 and 17. This filling meanspreferablycomprises strands 1Q of an inexpensive material such, for example, as cotton. arranged between the plies 30 and 31, in the mannerclearly illustrated in Figs. 3 and 4.

'These' strands extend the full length of the portions or pads wand 17 I are formedby ,weaving" the strip,

Fig. 4; While these cushioning described, six tubular portions respectively, thisis by strip and not only support the tubular porprovide a resilient filler of an tions, but also inexpensive character. By means of this construction, the cost of manufacturing channel lining is materially reduced. I I 1 It is apparent from the above description that by prov ding afiller of lessexpensive material the cost of such a channel lining is materially reduced. The fillers also (20- v operate with and reinforce the tubular portionsto provide cushioning pads'of substantial thickness 'which resiliently support thesash and hold it against vibration. pads are adapted for use with materials of an inexpensive .nature,'the sash engaging surfaces thereof are pleasing in appearance, durable, a friction reducing quality. I

L Fig. 5f shows-a mo the form of a strip of textile material, proglass dified channel lining, in 5' and of I vided with six spaced cushioning pads 16a and 17a which are similar to, but arenarrower than, the pads 16 and 17 above described. Narrow breaks 19a are provided between the pads, and thin marginal portions 20a extend outwardly beyond the pads 16a and are arranged to be held by suitable stiffening .and supporting means, hereafter described. The pads 16a and 17 a are disposed on the sides and bottom, respectively, of the window runway, and are constructed inthe same manner as the pads'16 and 17 above described. 'While Figs. 2 and 5 show a. channel lining provided with three and way of illustration only, and it is to be understood that any number of such portions maybe used. a

The lining above'des'cribed may be rein forced by any suitable stiffening and supporting means such, for example, as the channel member illustratedin Fig. 1. This channel member is preferably of .rigid sheet material formed to provide a bottom 45 and'side walls 46. The free edges of the side walls are reverselybent to form flanges 47 arranged to engage and hold the marginal POT-1 tions 20 or 20a to retain the lining in posi-. .tionin the channel member. Therlgid channel-member with its cushioninglining is disposed and held in place in a suitable groove "formed in the windowframe of the vehicle.

It is apparent from the above description that the present invention provides an efficient channel lining which is of a durable nature and adaptedfor usewith inexpensive materials." Inaddition', the sash engaging portions of the strip are. of a wear-resisting and frictionreducing quality, and are sup- .ported'by a filling of permanently resilient cushioning material. Such a lining aflords the advantageousfeatures? of the mdreexpenslve llnings", and at the same time is adapted v for use with materials of an inex vpensive nature so as to prov de a hmngna pable of being manufactured at a minimum of cost.

While certain embodiments of the invention have been disclosed, it is to be understood that the inventive idea may be carried out in a number of ways. This application is therefore not to be limited to the precise details described, but is intended to cover all variations and modifications thereof falling within the spirit of the invention or the scope of the appended claims.
